Permanent-magnet suction lift device utilizing magnetic module

Abstract

The invention discloses a permanent-magnet suction lift device utilizing a magnetic module. The permanent-magnet suction lift device mainly consists of a plurality of magnetic modules, a top plate, a mechanism fixing and limiting module and a drive mechanism, wherein the magnetic modules are fixedly arrayed and combined on the top plate and are all synchronously controlled by the drive mechanism to carry out magnetic circuit conversion so as to enable the suction lift device to externally generate or eliminate a suction force. According to the permanent-magnet suction lift device utilizing the magnetic module, a unit formation mode is adopted, the number of units can be freely combined, and the suction force and the magnetic depth of the suction lift device can be controlled by utilizing a magnetism regulation unit, so that the suction lift device has an excellent suction lift capacity.

Description

technical field [0001] The invention relates to a permanent magnet hanger, in particular to a permanent magnet hanger using a magnetic module. Background technique [0002] At present, there are permanent magnet hangers on the market that control one-way rotation through ratchet wheels, and the transmission part is composed of chains or gears. Most of them control the suction force generated by the hanger by rotating the magnetic system on a vertical plane. The method has the disadvantages of large reluctance and large loss of magnetic system suction, and these suction hoists have weak transmission mechanisms to control the magnetic system during use, and poor synchronization when multiple cranes are connected; at present, the permanent magnetic suction on the market None of the hangers can achieve the function of magnetic adjustment, and the ability to absorb and lift thin plates is extremely poor. For example, a YX4 type permanent magnet hoist on the market, its transmiss...

[0002] At present, there are permanent magnet hangers on the market that control one-way rotation through ratchets, and the transmission part is composed of chains or gears. Most of them use the vertical plane to rotate the magnetic system to control the suction force of the hanger. The method has the disadvantages of large reluctance and large loss of magnetic suction force, and during the use of these suction hoists, the transmission mechanism has weak control over the magnetic system, and the synchronization is poor when multiple hoists are connected; at present, the permanent magnet suction on the market None of the hangers can achieve the function of magnetic adjustment, and the ability to absorb and lift thin plates is extremely poor

For example, a YX4 type permanent magnet hoist on the market, its transmission structure uses a lever to drive the ratchet shaft to rotate, and then drives the magnetic system to rotate through the driving sprocket and chain on the ratchet shaft, and the magnetic system uses horizontal axis rotation to control the magnetic system conversion. , when the magnetic system of this type of product is combined together, the suction capacity of the magnetic system is greatly reduced compared with that of a single magnetic system. The rotation of the magnetic system is controlled by the sprocket chain, and the rotation error is large. The magnetic system conversion control is cumbersome and the synchronization is poor
